@PriestessDreadful If you are not above using CC (maybe for yourself, not for uploading), you can always recolor the windows you are using now, it's very easy to do using GIMP and Sims4Studio :)
For the fence, you can try what clousinators said, but it won't fix it. The issue is that the wall of your roof overlaps the fence and makes the fence disappear. You will see that wall > fence always... even if they are different heights. Make your roof 1 tile wide instead of 2, then extend te eaves up until you reach the fence (shift + click and drag those eaves). Since the roof wall doesn't touch it, it won't disappear anymore ;)
